For decades, combustion researchers and engine companies have been seeking to understand how these gases are produced during combustion so that they can find ways to reduce them. Now researchers have synthesized more than a decade's worth of combustion studies to create a new overarching model of how nitrogen oxides are produced.
With the growing global demand for sustainable and energy-saving products and processes, biosurfactants have come under the spotlight in recent years. A new study reviews their use in biotechnology applications, focusing on microorganisms in cold habitats.
The team developed an iridium catalyst with only two active metal centers. Most significantly, experiments revealed the catalyst to be a well-defined structure, capable of serving as a productive platform for future research on solar fuel synthesis.
In a new Perspective article, researchers are aiming to tackle a fundamental debate in key reactions behind fuel cells and hydrogen production, which, if solved, could significantly bolster clean energy technologies.
